If you have between 1 and 50 full-time equivalent employees, you generally qualify for small-group coverage and may be eligible for the Small Business Health Care Tax Credit; cross 50 full-time equivalents and you take on Applicable Large Employer obligations instead. The first move is simple: calculate your FTE count using an IRS tool or a licensed agent, then match your number against the thresholds below before you shop for a plan.
TL;DR:
- Count employees working 30 or more hours weekly as full time, then divide monthly part time hours by 120 and add the resulting FTEs.
- SHOP generally requires at least one common law employee beyond the owner; an owner only business cannot qualify for group coverage.
- The tax credit requires fewer than 25 FTEs, average wages below a cap, at least 50% employer payment toward employee premiums, and SHOP enrollment.
- Affiliated businesses may be aggregated; employers reaching 50 FTEs generally must offer affordable, minimum value coverage and file annual Forms 1094 and 1095.
- State participation thresholds vary, but the November 15 to December 15 enrollment window generally waives minimum participation rules, helping groups that otherwise fall short.

What group health insurance is and who the small-group rules cover
A group health plan is coverage an employer arranges for a defined group of employees, usually with the business paying some or all of the premium. Small-group status typically applies to employers with 1 to 50 full-time equivalent employees, though a few states allow groups up to 100 to use SHOP and similar small-group rules.
This threshold matters because it determines which doors are open to you:
- Small employers can generally shop through SHOP and may qualify for tax credits.
- Larger employers face Applicable Large Employer duties instead of small-group flexibility.
- Your size also affects which state and federal participation rules apply to your plan.
Knowing which side of that line you fall on shapes almost every decision that follows, from which plans you can buy to what paperwork you owe the government.
How to count employees and calculate full-time equivalents
Full-time generally means working 30 or more hours a week. To find your FTE count, add your full-time employees to a converted number from your part-timers: total part-time hours worked in a month, divided by 120, gives you the part-time FTE figure. Add that to your full-time headcount for your total.
- Count employees working 30+ hours weekly as full-time.
- Add part-time hours for the month and divide by 120.
- Combine the two figures for your total FTE count.
Say you have 15 full-time employees and four part-timers who together worked 240 hours in a month. That’s 2 additional FTEs, bringing your total to 17, comfortably inside small-group territory.
Owners with related businesses should also check aggregation and controlled-group rules, since the IRS counts commonly owned or affiliated entities together when determining employer size. Keep payroll records on hand in case a carrier or auditor asks for verification.
Pro Tip: Run your FTE count through an official calculator every time your headcount shifts by more than a person or two. Small changes near the 50-employee line can change which rules apply to you.
SHOP eligibility and the Small Business Health Care Tax Credit
To qualify for the SHOP Marketplace, you generally need 1 to 50 full-time equivalent employees, at least one common-law employee on payroll who isn’t just an owner or spouse, a plan offered to your full-time staff, and a primary business address in the state where you’re enrolling, according to HealthCare.gov. An owner-only business typically cannot enroll in a group plan until it has at least one bona fide employee.
The Small Business Health Care Tax Credit adds another layer worth checking:
- Available to employers with fewer than 25 full-time equivalent employees.
- Subject to an average annual wage cap for your staff.
- Requires the employer to pay at least 50% of employee-only premium costs.
- Generally requires enrollment through SHOP to claim the credit, per HealthCare.gov.
If you’re unsure whether you meet these marks, a SHOP eligibility calculator or a conversation with a registered agent clears it up fast.
Applicable Large Employer rules and shared responsibility basics
Reaching roughly 50 full-time employees, counting full-time equivalents, generally makes you an Applicable Large Employer under IRS rules, and commonly owned businesses are aggregated together when calculating that number. Crossing this line changes your obligations substantially.
- ALEs must offer affordable, minimum-value coverage to full-time employees and their dependents.
- Failing to do so can trigger an IRS payment if an employee receives a premium tax credit through the Marketplace, as outlined by the IRS.
- ALEs also take on annual reporting duties using the Form 1094 and 1095 series.
If you’re near the 50-FTE mark, it’s worth running the numbers each year rather than assuming last year’s status still applies.
Participation requirements, minimum enrollment rates, and state differences
Insurers often set a minimum participation rate, the share of eligible employees who must enroll, before they’ll issue a small-group policy. Many states follow a common range near three-quarters, though some set their own figures, according to CMS/HealthCare.gov SHOP guidance.
- Federal law under the PHS Act limits how aggressively insurers can use participation minimums to deny coverage to otherwise eligible small groups.
- States can set their own minimum participation rates within that framework, so your number depends on where you’re located.
- The November 15 through December 15 open-enrollment window is generally exempt from minimum participation requirements, giving groups a real path to coverage even if they fall short the rest of the year.
A SHOP minimum participation rate calculator can tell you quickly whether your current enrollment clears your state’s bar.
Waiting periods and effective dates employers need to plan around
Federal rules cap the maximum waiting period for new employees at 90 days, meaning coverage must start no later than the 90th day after eligibility begins, under PHS Act Section 2708 guidance from CMS. For employers hiring variable-hour staff, measurement and stability periods add another layer.
- A measurement period tracks hours worked over a set stretch to determine if an employee averages full-time status.
- The stability period that follows locks in that employee’s coverage status regardless of hours worked during that stretch.
- A measurement period combined with an administrative period generally cannot push the start of coverage beyond 13 months plus a short administrative buffer from the employee’s start date.
Lining up your measurement periods with your waiting period in writing avoids accidentally breaching the 90-day cap for employees whose hours fluctuate.
Who counts toward your headcount and eligibility
Not everyone on your payroll or in your workforce counts the same way. A business owned and run solely by its owner, with no other staff, generally cannot establish a group plan until a common-law employee joins, per HealthCare.gov.
- Independent contractors who receive a 1099 typically do not count toward your group eligibility or FTE total.
- Part-time employees count toward your FTE calculation but aren’t always required to receive a coverage offer.
- Seasonal workers often have separate counting rules, so check your part-time coverage options before assuming a seasonal hire changes your status.
Getting this part right keeps your FTE math accurate and prevents surprises when a carrier reviews your application.
Required documents, notices, and filings to keep on hand
Once you have a plan in place, a handful of documents become part of running it correctly. The Summary Plan Description explains plan terms in plain language and must be provided to participants, a requirement the Department of Labor spells out directly.
- Provide the Summary Plan Description to every enrolled participant.
- File Form 5500 when your plan meets the size and type thresholds that trigger it, following EBSA/DOL guidance.
- Keep enrollment records, signed plan documents, and proof of coverage offers organized and accessible.
Pro Tip: Store your SPD, enrollment forms, and offer letters in one folder from day one. Scrambling for them during an audit or a employee dispute costs far more time than organizing them up front.
Our guide to small-group plan compliance walks through these documents in more depth if you want the fuller picture.
Practical steps to move from eligibility check to live coverage
Once you know your FTE count and eligibility status, the path to an active plan follows a predictable sequence.
- Calculate your FTE count and confirm whether you fall into small-group or ALE territory.
- Decide between SHOP, a direct carrier, or a broker based on your tax-credit eligibility and plan preferences.
- Gather payroll records, employee hours, and dependent information for enrollment.
- Set your contribution level, typically at least 50% of employee-only premiums if you want the tax credit.
- Choose your enrollment window and confirm it with your chosen carrier or SHOP.
Remember that claiming the Small Business Health Care Tax Credit generally requires enrolling through SHOP rather than buying off-exchange. Build in a few weeks for gathering paperwork and underwriting before your target start date, and loop in a SHOP-registered agent or licensed broker early if any step feels unclear.

FAQ
What is a group health insurance plan?
A group health insurance plan is coverage an employer arranges for a defined set of employees, typically with the business contributing toward premium costs. It differs from individual coverage because eligibility, enrollment, and pricing are based on the group as a whole rather than one person’s application.
What are the main types of insurance a small business should know about?
Beyond group health coverage, employers commonly encounter dental and vision, life insurance, short-term disability, critical illness, and accident insurance as supplemental options. Auto, property, and liability insurance round out the coverage types most businesses carry, though those fall outside group health plan rules.
Is health insurance legally required for U.S. employers?
There’s no federal law requiring every employer to offer health insurance, but Applicable Large Employers, generally those with 50 or more full-time equivalent employees, can face a payment if they don’t offer affordable, minimum-value coverage and an employee receives Marketplace subsidies, per the IRS. Smaller employers can choose whether to offer coverage.
How many employees do I need to qualify for group health insurance?
Most small-group plans and SHOP require at least one common-law employee beyond the owner, with eligibility generally extending up to 50 full-time equivalent employees, according to HealthCare.gov. An owner with no other staff typically cannot start a group plan until that first employee is on payroll.
Can a business with just two employees get group health insurance?
Yes, a two-person business, one owner plus one common-law employee, can generally qualify for small-group coverage and SHOP eligibility as long as the employee isn’t the owner’s spouse. Participation requirements and state rules still apply, so checking your state’s minimum participation rate is a useful first step.
